I bought this book for my son when he was 3 months thinking it may be a little early and he would play later. Well, actually it is one of those favorite toys. From the first day I read him the story, pointing to the drawings and he looks good every time. He grabs the book itself and turns the pages! I have not tested in the bath because my son is only four months but I'm sure he will be delighted to also find it in the bath!
